RESPONSE ANALYSIS OF PILES UNDER LATERAL LOADS

Abstract

ABSTRACT As a foundation problem, the analysis of a pile under lateral loading is complicated by the fact that the soil reaction is dependent on the pile movement, and the pile movement, on the other hand, is dependent on the soil response. Thus, the problem is one of soil-structure interactions. Many methods such as the subgrade reaction method, the elastic continuum approaches that have been developed for the analysis of laterally loaded soil-pile system modeled piles as a flexible beam. But the available experiments demonstrate that the displacement field around a laterally loaded pile is significantly different from that around a beam overlying on an elastic medium. Thus, different modulus for beams and lateral piles should be adopted. It is with this background in this thesis an attempt has been made to implement a load transfer approach to simulate the response of laterally loaded single piles embedded in a homogeneous medium, by introducing a rational stress field. In the pres...
